Was the credit-card "overhaul" hailed as "limiting the greed" of the issuers another failure of Obama?

Just another example of when ignorant and arrogant politicians think they will get all of their promised "benefits" with zero cost. When you put a cap on what a lender can charge to a risky borrower for high risk lending, you get less of that credit available. And higher costs for that credit that remains. And higher costs to good customers. You get the point.
